I have one of the Bushido Tactical slings that Wade Rorich personally made for me when I was in Orlando. It is pretty nice and I would not feel under equipped with it if I were to use it on my rifle overseas.

Pair it with the single point sling plate or bolt on adapter of your choice and you can go from two point sling to single point quickly and easily giving you the best of all worlds and something you can set up for your specific purpose at the moment.
Here is a video from Busido Tactical at SHOT Show featuring the sling:
